Update cros_ec_lpc_pm_ops to call cros_ec_lpc_suspend() during PM
.prepare() and cros_ec_lpc_resume() during .complete. This allows the
EC to log entry/exit of AP's suspend/resume more accurately.

I don't see why that logging noise is necessary and/or adds value. If
every driver did that, the entire kernel log would be polluted by
similar messages.
